Abstract
Artificial joints are used when joints lose their function. The artificial joint is placed at the correct position by surgery of an expert surgeon or robot-assisted surgery. The surrounding bone grows and bonds to the surface of the artificial joint after the insertion without any adhesive. The primary stability is defined as stability before the fixation of the artificial joint, and stability after the fixation is called the long-term stability. In case of a femur-implant system, the primary stability evaluation is performed by the relative displacement measurement under a repeated load immediately after the insertion of the artificial joint. For more accurate stability evaluation, the accurate measurement of the penetration displacement of the artificial joint to the bone and the rotation angle of the artificial joint is essential. In this study, we used a relative displacement measurement method for the primary stability evaluation of the femur-implant system. By using this method, we comparatively evaluate the primary stability for different surgical methods and stiffness of the cadaver femur-implant itself.
